Sony's PlayStation Network Game Archives service has until now been focused exclusively on classic PlayStation releases. Today, Sony took an unexpected turn with the service, offering, for the first time, games from a different platform.

The honors go to the PC Engine, or TurboGrafx-16 as its known overseas. Bomberman '94, New Adventure Island (Takahashi Meijin no Shin Boukenjima), Sengoku Mahjong, and Devil Crush are available starting today, priced at the standard Game Archives going price of ¥600. The games are playable on both PlayStation 3 and PSP.

Classic games from something other than PlayStation. Could other platforms follow?

In a statement today, Sony said to expect more PC Engine titles on the service in the future.

The company did not mention the possibility of other platforms appearing on the service. However, the availability of TurboGrafx titles suggests the possibility of games from platforms such as Genesis and NeoGeo, similar to Nintendo's Virtual Console.
